So the cardboard helps the Glyphosate?

No, the cardboard smothers whatever the glyphosphate didn't kill. If
you don't want the agent orange approach, run over the whole thing
with a good strong mower, then mulch heavily with cardboard, dead
leaves, anything that makes a barrier and will rot. If you do this in
the fall, a rotovator will finish the job in the spring. Also a good
way to convert useless sod into useful veg garden! (Am I the only one
who finds the garden space creeps into the lawn?)

Thought so!
Are you in the UK?
I think not. If you give advice from another country, or even continent,
you should say so. The USA has very different climate changes from us in
the UK.

Doesn't sound US-based to me - most Americans I know, would say
'rototiller', rather than 'rotovator'.
